He has a gray shell, gray skin color and a white head, which has a star birthmark over his left eye. He was named after talk show host and singer-songwriter, Morton Downey Jr.
His first appearance was in Super Mario Bros. 3, where he is the boss of the second world. In Super Mario World, his appearance is altered slightly, with his color being green, and he is the boss of the second world. His next appearance isn't until New Super Mario Bros. Wii, then New Super Mario Bros. 2 and finally New Super Mario Bros. U. He also appeared in Mario & Luigi: Superstar Saga, as a boss in the final stretch leading up to Bowser
